<h1>FAQ</h1>
<p><b>Introduction :</b><br/>
The software <i>Lignes de temps</i> is divided in two parts: system and interface.
<br/>The first one is not visible for users; it allows to record the work done (notes, sequences, rough-cut) in a file. It also permits to launch programs necessary to import an audio or video file. These programs encode video in order that it can be visible in the interface and that it can produce the shot by shot and the sound wave.
<br/>The interface is composed by all the elements visible and controlled by users. It is composed by the top left menu (File, Display) and by three windows: Informations, the media player, and the one who displays the lignes de temps.
<br/>The two parts of the program are connected but the communication can sometimes be interrupted, without any notification. In this case, the work can not unfortunately be recorded. The Institute for research and innovation works on those different problems.
For any information, feedback or problem : <a href="mailto:contact@iri.centrepompidou.fr">contact@iri.centrepompidou.fr</a><br/>
A work on <i>Lignes de temps</i> is saved in a project file (ldt extension) which holds references towards the media used and the personal data (notes, sequences, rough-cut).
The non-personal data on one media (shot by shot and sound wave for example) are recorded in an iri extension file.
<ul>
<li><b>I use a Mac, how can I know which is my configuration ?</b><br/>
To know if your computer is "Intel" or "Power PC", you have to go in the Apple menu up left on the screen. In the menu, click on "About this Mac". The line "Processor" indicates the type of configuration "Intel" or "Power PC".<br/>
After many tests, it seems that <i>Lignes de temps</i> just settles on the computers with the operating system 10.5 called "leopard", the 10.4 one called "tiger", the Intel processor, or with the Power PC processor.</li>
<li><b>I do not succeed in displaying movies :</b><br/>
To display those lignes de temps, you have to click on the movie title in the lignes de temps window then on the tab "Cuttings". In this tab, appears the list of the available sequences; you just have to click on one of them to display the corresponding ligne de temps.</li>
<li><b>I do not succeed in importing an audio or video file :</b><br/>
You have to make sure that the file extension can match. <i>Lignes de temps</i> takes into account avi, mpg, mov, flv extension for video and mp3 for audio.
Then, even if this one is accepted, the encoding can not match with the program (ffmpeg) which transforms this file in a video readable in <i>Lignes de temps</i>, that is to say in the flv format.
Even if the file extension is correct, some characters block the import. Thus, you should prefer naming your file without the following characters : accented characters, space, ç, #, &, %, !, *, (), [], |, {}, :, ;, @.</li>
<li><b>I do not succeed in saving my work :</b><br/>
As it is explained in the introduction, this problem can come from a communication failure between the interface and the program part which records the work in a file.
To record the works, we can go through the up left menu (Fichier -- Enregistrer) or through the hot key Ctrl+S on PCs and Apple+S on Macs.
In general, when a work has been modified since the last recording, a star appears close the movie title in order to warn about a required recording.</li>
